ReceptionRating · Positive reviews · Number of ratings

Tape Measure Camera Ruler 3D holds the better App Store score, 4.2 against 4.0.

Written reviews complicate that: 45% of 100cm Ruler's written reviews are positive against 23% of Tape Measure Camera Ruler 3D's, so the app with the better star average is not the one people write more warmly about.
